Here in Ontario Doug Ford love Premier took out the drive clean program where you had to go in every two years hook your car up to a machine and make sure it was up to code. If you had any codes showing you would have to get all those repairs done first. Now that shit's gone it'll be straight pipes and Cherry Bomb mufflers. Thanks guys great video

[@GearsAndTech]

Hah, you guys will be like Albertans in no time! We don't require cats here because we still drive our farm vehicles into the hay fields. A glowing red cat can cause a field fire. So they are not mandated on any vehicle. Welcome to the wild west! I knew I liked that Doug Ford guy!

ACTUALLY even though Herr Ford deleted the drive clean program you can still face hefty fines for modding your emissions system. The sure fire tell by police? Your loud exhaust as well as the smell of the uncatylized exhaust. I cannot confirm but I've been told that cops now carry db meters to measure the sound of your exhaust. They can immediately pull your plates and have you towed to an inspection centre.

I'm all for hella power and straight piped exhaust, but it's a good way to kill children and cause insane amounts of cancer via inhalation of the shit the exhaust spews. It even was the cause of all that acid rain that was common during the 70s and 80s, and I'm clueless where nearly all cars having cats now it's not a problem anymore. Would you say you wish gasoline was still leaded? Probably not, and pure exhaust fumes are almost as harmful as the vaporized lead that people back in the day had to inhale constantly.

The point of a cat is to charge rediculous prices for something that doesn't really do shit except cost you money....by restricting your motor then when they go out you gotta spend a shitload....plus you gotta fuck with o2 sensors as well. You can cut them out and cut you some pipe with the o2 sensor threads and weld that back in so you don't throw sensor codes

[@kindellhutchins5653]

if i just want it to be a little louder can i just drill a couple holes? or do i need to hollow it out completely? i don’t want it super loud just a little louder

[@GearsAndTech]

You could drill holes yes. It would be a long drill bit required. Or just pound the pipe through the middle and not around the edges

[@Yixdy]

Usually this will cause a hissing sound, and depending on where your cat is it could also let carbon monoxide and other toxic fumes into your cars cabin if you're idling while stationary, and these chemicals build up in your body over time so avoiding them in the first place is a great idea. Plus holes before the muffler will be much louder than you expect, because they aren't being muffled, a few holes in the cat may end up louder than hollowing it, or replacing it with a straight pipe. I'd recommend drilling holes into the muffler, near the far end of it and checking how loud it is with each hole by starting the car every time

[@GearsAndTech]

Exactly. Basically it's a bad idea

[@EarthSurferUSA]

@@GearsAndTech It may be possible for loose particles from the cats to actually make it to the engine values during operation. I don't work on 4-stroke engines, but I do build 2-stroke engines for a living. I thought it was impossible, but I have seen sand enter an "exhaust can" on RC cars in sand dunes, and fill the engine up from the exhaust side of the engine. I would think it was "sound waves" bouncing back, and carrying the dirt into the engine. A half gutted cat will still change direction of the sound waves, and they do have a force.

That's a tough one. Here in Alberta you can't In fact, you can buy a brand new truck off the dealership with no mud flaps, and on the way home get pulled over by the police for not having mud flaps. You can't sue the dealership then So, it's unlikely you can sue a shop for no cat. You always have the right to do a pre purchase inspection at a shop of your choice before buying.

[@TheIrongutz]

Beware, gutting your converter may damage your engine on vehicles later than 96 due computer pollution sensors which monitor upstream and downstream exhaust gases. Your vehicles computer use the data to adjust air/fuel ratios and can cause your engine to run too lean or most likely rich which can cause poor fuel economy and excess carbon buildup.

[@Subi_doo]

You’ll need what’s called and o2 Fowler plug adapter to pull the o2 further out of the exhaust stream so it read correct. People using race pipes use these where there is no cat in place at all.

[@darronpattel]

Ya, it's not as simple as the guy in the video puts it: with all the tuning and other exhaust mods you would have to make for it to be safe for the engine and to get enough horsepower for it to be worth it (especially on vehicles with smaller engines), but it is worth doing if you got an old cat in a lot of cases just because they can get expensive. If you're buying a new car fresh of the lot, maybe leave it in till its used up though, that's how I see it....

[@Subi_doo]

@@darronpattel personally I think it does more harm than good. It’s perfect if you need to look stock, but with a hollow barrel larger than the diameter of the pipe coming in and out, it creates a sport for turbulence, which can create heat from exhausts that can’t get out and swirl around inside the gutted cat, and or slow your exhaust flow down, which can be why some people lose power.

[@darronpattel]

@@Subi_doo Exactly, its stuff like that he shoulda been mentioning. I'm a welder because my dad was a welder by trade so I made my own straight pipe in less then an hr and im not even a pro welder or anything. So if you get the right person to do that, tune it and maybe put some new headers on then in most cases ur good, but he mentions none of that in the vid.

[@darronpattel]

[@95Sn95]

Magnesium? It's ceramics with precious metals like platinum radium in palladium , I don't know what you got your info but magnesium is not a precious metals in cats and it's not precious its very similar to aluminum. If your going to make automotive education do research before schooling folks and magnesium dust isn't "toxic" per se obviously dust or fumes from melting is not good for you to allow to enter your respiratory system and excessive fumes from welding it can cause flu type symptoms but dust isn't going to do that.

[@GearsAndTech]

I'll see if I have that bag of precious metals anywhere still. Are you willing to put your money where your mouth is? I'll shake the bag up to get a good cloud of dust, then you just need to huff that dust for 1 minute to show all the viewers at home how safe it is

[@LemonAutomotive]

Will this hurt my car tho?

[@Yixdy]

Removing it completely without installing a pipe or something in it's place will, depending on how short this makes your exhaust that is. Some turbo vehicles lose a bit of power because the turbo will not operate at it's full potential, and unfortunately some older (as in 1996 and older) may go into limp mode, which will cut your horsepower down significantly, among other things. But generally, if the catalytic converter is clogged it will actually restore power if you do this

[@EarthSurferUSA]

@@Yixdy A clogged cat, (and even some new ones IMO), will raise engine temps a lot, (even if the engine management system controls the water temp on your gauge). You will actually increase the life of your engine by reducing the temps if that is a problem. If your car runs great when cold, hammer it and it goes,---but loses that after it is warm, and you have some mileage on the car,---put on the top of your suspect list, "clogged cats". You also probably notice your heater blowing hot air, (from cold), real fast, and quite a bit of heat under the hood when you open it after operation.
